Looks like I have a RAM problem :/ Just running a full memtest while I go to work but I've had a few app exception issues pop up, one in Prime95 just now and I think it was RAM. I'm running at 1600 as spec.. maybe the timings aren't right? Not sure. This is the RAM i bought: http://www.ebay.com.au/itm/Samsung-...CL11-Registered-REG-ECC-Memory-/231910086281? Mathuisella is there any specific timings I need to change in the Lenovo BIOS?
